Target Species

Target species are potential County Records - species not yet documented in the county. 'Local Obs' is Local Observations and indicates the number of times that the species has been observed in adjacent counties since 2000, and '# of Counties' is the number of adjacent counties in which those recent observations took place. Zero local observations or recent counties means the existing records are historical. 'Peak Active' is a relative description of when the species has been known to fly.

Places to visit

  • Over 25,000 acres of the 178,000 acre Wayne National Forest are located in Monroe County

  • Lamping Homestead Recreation Area has a pond with easy access to about 50% of the perimeter, and it is kayak accessible. $10/night but camping gear needs to be hauled to official sites and distances to those sites will vary. At the time of this writing, google maps misses the RT 307 turn off.

  • Ring Mill Campground provides access to a creek. The climb down is medium-hard due to the steep bank. The location is best approached from Rt 68 North. Low Gap Jericho Rd. is often a washout just east of Harmon Ridge on Low Gap requiring 4WD to get through. $10/night to camp but you can park on site.

  • Knowlton covered bridge provides easy access to the Little Muskingum River.

  • Monroe Lake is a 39 acre artificial lake within the 1325 acre Monroe Lake Wildlife Area just south of the town of Malaga. The boat launch on the north west side provides easy access to some of the bank, and it is kayak accessible. Take SR 145 to 1001/Main Cross St. The southeast area of the lake provides down to the bank on the dam and around to the north east leg. It can be worth it to walk south down to the dam outlet at the creek. Expect moderate climbs. Parking is located off of SR 800
